The protagonist, an 8-year-old girl who is actually a modern-day terminally ill patient who transmigrated into this world. In her previous life, she lived only to twenty and spent her memories in hospitals. She greatly admired Zhao Zhen as a historical figure. She chose to go north with her grandmother instead of fleeing south with her uncle Yu Xuandu, wanting to live past twenty and experience growing old slowly rather than die in a gilded cage in the south. She is firm-hearted, clear-eyed, and possesses peerless strength of character beyond her years.
